Gastrointestinal stromal tumor (GIST) is a rare type of cancer that affects the gastrointestinal tract. It usually develops in the stomach or small intestine, but can also occur in other parts of the digestive system. GISTs are caused by mutations in the KIT or PDGFRA genes, which control the growth and division of cells in the body.
Symptoms of GIST can include abdominal pain, bloating, nausea, vomiting, and weight loss. However, these symptoms can also be caused by other gastrointestinal conditions, so it is important to see a doctor for an accurate diagnosis.
If you have been diagnosed with GIST, it is important to work closely with your doctor to determine the best course of treatment. Your doctor may refer you to a specialist in gastrointestinal cancers, who can provide more specialized care and support.
In summary, GIST is a rare type of cancer that affects the gastrointestinal tract. Symptoms can include abdominal pain, bloating, nausea, vomiting, and weight loss. Diagnosis involves a physical exam, blood tests, imaging tests, and a biopsy. Treatment may involve surgery, chemotherapy, radiation therapy, or targeted therapies. If you have been diagnosed with GIST, it is important to work closely with your doctor to determine the best course of treatment.
